Commenting code within JSX blocks uses incorrect comment format

[TheAndrewJackson]

Summary

The normal typescript and javascript comment syntax (//) is correctly applied in standard ts/js. JSX markup inside ts/js files requires block comments within curly braces ({/* */}). <C-c> is applying the normal syntax (//) inside JSX blocks.

Reproduction Steps

commenting.in.JSX.mov

I tried this:

1. hx file-with-jsx-markup.tsx
2. create a react component with a minimal render function
3. try commenting out some text within the JSX markup <C-c>

I expected this to happen:
4. the code is commented out with the block syntax {/* */}

Instead, this happened:
4. the code is commented out with the standard syntax //
